Description

Technical Field

[0001] The invention relates to the technical field of motor processing equipment, in particular to a pull rod type winding head. Background Art

[0002] The stator of the motor consists of a stator core and a winding wound on the stator core. The wire group is made of enameled wire. In the early days, the enameled wire was wound on the stator core by mechanical winding. During the mechanical winding, the core and the wire mold are generally assembled manually, and then the whole is installed in the fixture of the winding machine and the copper wire is wound by the winder. This working method of core assembly is not only cumbersome and time-consuming, but also reduces production efficiency. In addition, the operator needs to reach into the fixture to take out the core every time he winds a core. The hands frequently reach into the workbench area of ​​the fixture, winder and other components, and the safety hazard is prominent.

[0003] The use of a winding machine for step-by-step winding improves the efficiency of winding and at the same time improves the safety of winding. Since each winding head is provided with nine sets of wire nozzle structures, the nine sets of wire nozzle structures are evenly distributed on the cover plate. However, for small winding heads, the circumferential space is small and insufficient to evenly distribute the wire nozzle mechanisms. The fixed-structure nine-set wire nozzle mechanism cannot be used for the small winding head of the winding machine. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] First embodiment:

[0035] See also Figure 1-6 The embodiment of the present invention provides a technical solution: a pull rod type winding head includes a lower cover assembly 1, the top of the lower cover assembly 1 is provided with at least nine first movable grooves 11, the outer side of the lower cover assembly 1 is provided with three mounting grooves 12, the inner wall of the lower cover assembly 1 is provided with at least nine limiting protrusions 13, the interiors of the three mounting grooves 12 are fixedly connected with a pin shaft pressure plate 2, the pin shaft pressure plate 2 is provided with a second movable groove 21, the interior of the second movable groove 21 is provided with a wiring swing arm 22, the wiring swing arm 22 is hinged to the pin shaft pressure plate 2, and the surface of the wiring swing arm 22 is provided with a support A support shaft 221, a first linkage protrusion 222 is provided on the inner side of the wiring swing arm 22, a second linkage protrusion 223 is provided on the top of the wiring swing arm 22, a push rod 3 is provided on the bottom of the lower cover assembly 1, at least nine sliding grooves 31 are provided on the outer surface of the push rod 3, at least nine linkage grooves 32 are provided on the outer surface of the push rod 3, a wire nozzle mechanism 4 is provided inside the first movable groove 11, a linkage slider 41 is provided on the bottom of the wire nozzle mechanism 4, an upper pressure cover assembly 5 is provided on the top of the lower cover assembly 1, and at least nine limiting sliding grooves 51 are provided on the bottom of the upper pressure cover assembly 5.

[0036] The upper pressure cover assembly 5 is the upper pressure cover of the wire nozzle, and is installed above the wire nozzle mechanism 4 through a limiting slide groove 51. The number of limiting slide grooves 51 is the same as the number of the wire nozzle mechanism 4 and the positions correspond to each other, so that the upper pressure cover assembly 5 can be stably installed above the lower cover assembly 1.

[0037] Since the circumferential space of the small winding head is small and insufficient to evenly distribute the nine wire nozzle mechanisms 4, the wire nozzle mechanisms 4 are movably installed on the lower cover assembly 1, wherein three groups of evenly distributed wire nozzle mechanisms 4 can be freely assembled and disassembled on the lower cover assembly 1 through three pin pressure plates 2, and the installation quantity of the wire nozzle mechanisms 4 can be controlled according to the requirements of use, thereby conveniently reducing the occupied space of the wire nozzle mechanisms on the upper pressure cover assembly 5.

[0038] Among them, three wire nozzle mechanisms 4 are hinged to three corresponding pin shaft pressure plates 2, and the other six wire nozzle mechanisms 4 are hinged to the inner wall of the first movable groove 11 on the lower cover assembly 1. The bottom of the wire nozzle mechanism 4 is provided with the same wiring swing arm 22 structure. The nine groups of wiring swing arms 22 are distributed on the same circumference and have the same structure. When the push rod 3 moves up and down, the push rod 3 can stably slide up and down inside the lower cover assembly 1 through the sliding structure of the sliding groove 31 and the limiting protrusion 13. When the push rod 3 slides up and down, it synchronously drives the first linkage protrusion 222 to transmit through the linkage groove 32. When the first linkage protrusion 22 is transmitted, the second linkage protrusion 223 is driven to rotate synchronously through the integrated wiring swing arm 22. When the second linkage protrusion 223 rotates, it transmits with the inner surface of the linkage slider 41 to push the wire nozzle mechanism 4 to slide left and right, thereby ensuring the stability of the adjustment of the wire nozzle mechanism 4.

[0039] The pin pressure plate 2 is spliced ​​and installed with the installation groove 12 on the lower cover assembly 1 by installing bolts. After the pin pressure plate 2 is installed, the wiring swing arm 22 on the pin pressure plate 2 is in the same relative position as the wiring swing arm 22 inside the first movable groove 11, so that when the push rod 3 is adjusted up and down, it can synchronously drive multiple groups of wire nozzle mechanisms 4 to move and adjust synchronously through the wiring swing arm 22 structure.

[0040] The three installation grooves 12 are evenly distributed on the outer surface of the lower cover assembly 1 , and the interiors of the three installation grooves 12 are interconnected with the interiors of the corresponding three first movable grooves 11 .

[0041] At least nine of the limiting protrusions 13 are arranged parallel to each other, and the limiting protrusions 13 and the first movable grooves 11 are arranged in a staggered manner.

[0042] The pin pressure plate 2 is mounted on the inner wall of the mounting groove 12 by means of bolts, and the interior of the second movable groove 21 is communicated with the interior of the first movable groove 11 .

[0043] There are at least nine wiring swing arms 22 , three of which are matched with the three pin pressure plates 2 , and the other six wiring swing arms 22 are matched with the other six first movable grooves 11 and are hinged to the lower cover assembly 1 .

[0044] The surface of the first linkage protrusion 222 is an arc-shaped structure, and the surface of the second linkage protrusion 223 is an arc-shaped structure.

[0045] The inner surface of the sliding groove 31 is slidably connected to the surface of the limiting protrusion 13, the linkage groove 32 is staggered with the sliding groove 31, and the linkage groove 32 and the sliding groove 31 are perpendicular to each other, and the inner surface of the linkage groove 32 is transmission-connected to the surface of the first linkage protrusion 222.

[0046] The inner surface of the linkage slider 41 is transmission-connected to the surface of the second linkage protrusion 223 . Sliding protrusions are provided on both sides of the linkage slider 41 . The linkage slider 41 is slidingly connected to the inner wall of the limiting sliding groove 51 through the sliding protrusions.

[0047] The vertical cross-section of the limiting slide groove 51 is an inverted T-shaped structure. The interior of the limiting slide groove 51 is interconnected with the interior of the first movable groove 11 . The thread nozzle mechanism 4 is arranged between the first movable groove 11 and the limiting slide groove 51 .

[0048] When in use, when the number of winding mechanisms needs to be adjusted, the upper pressure cover assembly 5 is preferentially removed from the lower cover assembly 1, and then the wire nozzle mechanism 4 corresponding to the pin shaft pressure plate 2 is moved upward and removed, so that the wire nozzle mechanism 4 is disengaged from the surface of the second linkage protrusion 223, the pin shaft pressure plate 2 is removed from the inside of the mounting groove 12, and then the pin shaft pressure plate 2 is taken out horizontally, and the wiring swing arm 22 inside it is pulled out synchronously, and when the wiring swing arm 22 is pulled out, the first linkage protrusion 222 is synchronously driven to horizontally disengage from the inside of the linkage groove 32, without affecting the wiring swing arm 22 inside the first movable groove 11 and the adjustment of the wire nozzle mechanism 4;

[0049] The number of pin pressure plates 2 can be removed according to the use requirements to meet the installation requirements of different space sizes. It has a wide range of applications and a simple and convenient installation structure.

[0050] Second embodiment:

[0051] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10Based on the pull rod type winding head provided by the first embodiment of the present application, the second embodiment of the present application provides another pull rod type winding head. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0052] Specifically, the difference of the pull rod type winding head provided in the second embodiment of the present application is that the pull rod type winding head also includes: at least three hook grooves 14 are opened at the bottom of the lower cover assembly 1, and the inside of the three hook grooves 14 are provided with a hook plate mechanism 6, and the two sides of the hook plate mechanism 6 are fixedly connected with a rotating shaft 61, and the two ends of the rotating shaft 61 are rotatably connected to the inner wall of the hook groove 14, the inside of the hook groove 14 is interconnected with the inside of the lower cover assembly 1, and the inner wall of the hook plate mechanism 6 is opened with a hook groove 62, and the inner surface of the hook groove 62 is clamped with a connecting mechanism 7.

[0053] The hook plate mechanism 6 can be rotated and adjusted inside the hook groove 14 via the rotating shaft 61 .

[0054] At least three hook plate mechanisms 6 are evenly distributed on the bottom of the lower cover assembly 1. The hook plate mechanisms 6 facilitate rapid docking between the connecting mechanism 7 and the lower cover assembly 1. When it is necessary to connect the connecting mechanism 7 and the lower cover assembly 1, the bottom ends of the three hook plate mechanisms 6 at the bottom of the lower cover assembly 1 are preferentially rotated to the side away from the push rod 3, and the connecting mechanism 7 is pushed into the inner side of the three hook plate mechanisms 6, and the bottom of the connecting mechanism 7 is connected between the hook grooves 62 on the three hook plate mechanisms 6. The connecting mechanism 7 is continued to be pushed upward, and the connecting mechanism drives the three hook plate mechanisms 6 at the top to rotate synchronously and automatically snap onto the outer surface of the connecting mechanism 7, thereby facilitating rapid insertion of the connecting mechanism 7 into the lower cover assembly 1.
